LPA bringing you the latest in DNA Collection 

LPA offers DNA Collection for less than half the industry standard cost per sample in North Carolina...

Brought to you by Laura Pettler & Associates...your new-age solution to age-old challenges.


The M-VAC Forensic DNA Collection System is a we-vacuum based DNA collection device that is helping investigations solve more crime. It has been used on dozens of cases and has produced DNA profiles numerous times when traditional methods such as swabbing and cutting have failed to produce viable results. It is ideal for touch DNA scenarios, and can capture many times more DNA material than other methods from porous surfaces like clothing or other fabrics as well as rough surfaces, such as rock, brick, or concrete. Investigators who are using the M0VAC System are seeing impressive results and are moving many cases forward. 

LPA brings you cutting edge technology...

The M-VAC's (microbial vacuum) patented collection method applies a sterile solution to the surface and simultaneously vacuums up the DNA material from the targeted substrate. The solution and DNA material are then captured in the attached collection bottle, which is then filtered and sent to the crime lab of your choice for analysis and processing. The M-VAC collection method is both scalable and more sensitive than traditional swabbing methods, so covering a larger surface area and/or collecting minute amounts of DNA is more likely.
